Lean right out of bed -- time to reveal bust (8)
I believe the answer is:
bankrupt
'bust' is the definition.
(I've seen this before)
'lean right out of bed time' is the wordplay.
'lean' becomes 'bank' (bank can mean to tilt).
'right' becomes 'r' (common abbreviation).
'out of bed' becomes 'up' (synonyms).
'time' becomes 't' (abbreviation).
'bank'+'r'+'up'+'t'='BANKRUPT'
'to reveal' is the link.
(Other definitions for bankrupt that I've seen before include "on the rocks" , "Penniless" , "Financially 'bust'" , "Skint" , "Unable to pay one's debts" .)
